英文:
Unable to record voice calls on Android 12
问题
recorder = MediaRecorder().apply {
setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION)
setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP)
setOutputFile(fileName)
setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB)
registerAudioRecordingCallback(executor, object : AudioManager.AudioRecordingCallback() {
override fun onRecordingConfigChanged(configs: MutableList<AudioRecordingConfiguration>?) {
super.onRecordingConfigChanged(configs)
configs ?: return
configs.forEach {
LogUtil.d("isClientSilenced=${it.isClientSilenced} \n" +
"devices=${it.audioDevice.address} \n" +
"effect=${it.effects.size} \n" +
"format=${it.format} \n" +
"audioSource=${it.audioSource}")
}
}
})
try {
prepare()
} catch (e: IOException) {
LogUtil.d("prepare() failed")
}
LogUtil.d("start record")
start()
}
The isClientSilenced method always returns true during voice calls, even if you are using AccessibilityService to record voice calls.

最后，我发现我必须使用VOICE_RECOGNITION模式，并且只有在不使用耳机时才能录音通话。
英文:
In the end, I discovered that I must use the VOICE_RECOGNITION mode, and recording calls is only possible when not using headphones.
